Activity monitor for pain management efficacy measurement

摘要

An activity monitoring system measures the effectiveness of pain management using using data from motion or activity sensors attached to the patient's body to compute measures of exertion level of a patient. Increased levels of exertion are an indication of successful pain management. The patient's walking gait smoothness and walking gait stability are also graded as indicators of pain management effectiveness. The motion or activity sensors may be part of a temporary stimulation system used during percutaneous trials, part of a permanent implanted system, or an independent sensor package carried on the patient's body. The particular location and axes of the motion or activity sensors may be chosen based on the location of the pain being treated. The effectiveness of a particular pain management stimulation parameter set is based on the statistics accumulated over a period of time, for example one hour.
